The 40 V Max. Brushless 28 mm Rotary Hammer delivers high performance with 2.8 joules of hard hitting impact energy. That impact energy allows you to drill holes in masonry up to a 28 mm diameter quickly and efficiently. Anti-Vibration Technology (AVT) actively reduces the tools vibration through a series of count weight mechanisms and vibration absorbing housing. These designs significantly reducing the vibration transferred to the user for more comfortable use of the tool over extended periods of time. In addition the HR001G is compatible with a wide variety of dust management options including the onboard dust extraction system DX12.
